(I posted this same post in the newbie forum and only got 3 responses hopefully i would get more in here)Ok so I ran a compression test today on my talon tsi and im wondering what the hell is goin on my numbers were 150-150-147-90 Is 90 really bad or ok or what? What should i do? The car is pretty much all stock, and i was wondering how would my motor be with boostin at 15 or 16psi?

90 is pretty low. A possibility is a bad headgasket.
